Technical characteristics

SURVEY MICROPROCESSORTECNAIR LV units are fitted with advanced SURVEY microprocessors which are designed to provide complete control of all the fundamental functions of close control air conditioning.

The microprocessor has a FULL GRAPHICS interface, with interactive icons and progress bars to make the controller user-friendly even for those who are not familiar with air conditioning equipment in either Data Centres or comfort cooling.

The SURVEY microprocessors can also:

■ Guarantee enhanced operating continuity thanks to the self-

diagnostic function and complete management of alarms.

■ Manage in an integrated manner the operation of the EEV valve and the DC INVERTER with verification of the

envelope of the compressors.

■ Present active graphic displays of temperature and humidity, daily and weekly and permit the user a high degree

of supervision of the general operation of the plant.

■ Guarantee integration with supervision systems and BMS through the RS485 MODBUS RTU serial

communication card.

The following examples illustrate some of the functions visualized on the display of the microprocessor:

5Technical characteristics

Important advantages obtained as a result include:

■ Power drawn by the fans is reduced by over 25% compared to fans using traditional AC technology.

■ Power drawn by the fans is reduced by about 15% compared to the previous generation of EC fans.

■ Noise levels are reduced by over 5 dB(A) at partial loads.

■ Risk to the plant is reduced as the mechanical parts are subjected to less use.

Thanks to integration with the SURVEY microprocessor, the EC fans can be controlled to:

■ Reduce rotation speed and therefore air quantity as the cooling capacity requirement decreases, thus making

possible a 50% energy saving, operating at partial loads, compared to a constant velocity system.

■ Maintain constant air quantity controlled in real time by differential pressure sensors, optimal control if F7 filters

are installed.

■ Maintain constant air pressure in the raised floor or in the compartmented areas in order to optimize air distribution

avoiding hot spots and to guarantee maximum modularity of the plant.

Technical characteristics

ADVANCED LOCAL NETWORKThanks to constant efforts in the research and development of control processes, TECNAIR LV has implemented an innovative management system for air conditioners in a local network (LAN), called SMARTNET.

SMART NET, unlike normal networks n+1 or n+n (which are still available, however), can maintain all the air conditioners in the network active at the same time.

Thanks to a powerful control algorithm designed to maximise the advantages of the local network, SMARTNET

permits:

■ Optimal and uniform distribution of the air and cooling capacity in the zones without air conditioners in standby

state which could create hot spots.

■ Average energy savings of over 60% due to the modulation of components at partial load (EC fans, DC

inverter, etc.).

■ Management of the AVERAGE READINGS of the temperature and humidity sensors fitted in the air conditioners,

guaranteeing the best management of conditions in the areas.

■ Management of the AVERAGE READINGS of the pressure sensors fitted in the air conditioners, guaranteeing

optimal air distribution in the areas.

Main accessories

BRUSHLESS DC COMPRESSORS WITH INVERTER TECHNOLOGYAdapting cooling capacity to the real requirements of the plant is one of the principal conditions of guaranteeing the flexibility required by the most advanced systems.

TECNAIRLV has adopted BRUSHLESS DC INVERTER technology in order to obtain this. Like the EC fans, also the compressors are fitted with BRUSHLESS motors driven by a special inverter designed to maximize the performance of the motor, especially at partial loads, control of which is integrated in the SURVEY microprocessor.

Thanks to the innovative BRUSHLESS DC technology, TECNAIR LV close control air conditioners can:

■ Maintain the thermo-hygrometric conditions of the controlled areas at a constant level, guaranteeing that the

set-point is respected even under partial loads.

■ Modulate the cooling capacity of the units between 20% and 100% of maximum capacity.

■ Reduce the annual energy consumption of the unit by over 70% (in partial load conditions).

■ Obtain an increase in energy efficiency (EER), since the power drawn by a BRUSHLESS DC compressor driven by

inverter reduces in proportion to the decrease in cooling capacity supplied (unlike other control systems which do

not reduce the number of revolutions of the compressor).

■ Increase the safety of the plant thanks to the innovative design of the compressors which guarantees perfect

return of oil even at minimum speeds.

■ Reduce noise levels.

EEV ELECTRONIC EXPANSION VALVEAn advanced control system is necessary to maximize the performance of direct expansion cooling circuits, especially in partialized conditions.

The EEV electronic expansion valves guarantee excellent control of the cooling cycle through the direct regulation of the main functional values.

Thanks to integration with the SURVEY microprocessor, the EEV electronic valves make it possible to:

■ Save energy, over the course of a year, by up to 25%, optimizing the performance of the cooling circuit compared

to a traditional TEV thermostatic expansion valve.

■ Visualize on the display the operating conditions of the cooling circuit in a simple and immediate way.

■ Manage the lowest possible value of overheating for the cooling circuit, maximizing the heat transfer of the

evaporating coil.

■ Allow the condensing temperature, in winter or at night, to drop to 35°C with a great reduction in the compression

ratio of the cooling circuit and therefore also of the power draw.

Main accessories

ELECTRONIC FANS IN THE ACC AIR-COOLED CONDENSERSThe demand for reduced energy consumption means that components with apparently limited consumption (such as air-cooled condensers) also require a substantial cut in the electricity they use.

For this reason, fans with BRUSHLESS EC motors can be selected also for ACC series air-cooled condensers.

Their use makes it possible to:

■ Save energy, at partial loads, by over 45% compared to a normal condenser with AC motors.

■ Reduce noise levels, at partial loads, by over 10% compared to a normal condenser with AC motors.

■ Obtain a wide modulation range, from 0% to 100%, of the nominal velocity of the fan, without the usual problems

relating to normal cut-phase controllers.

■ Manage, when external conditions permit, very low condensing temperature set-points (35°C),

while guaranteeing operation at high summer temperatures (condensing temperature 60°C).

The interest of the market in sources of renewable energy has led to the development of air conditioners with low environmental impact using the FREE COOLING function.

This system uses external air - a source of renewable energy – to cool the water in the Free Cooling circuit through an external dry cooler.

The Free Cooling circuit works instead of or in addition to direct expansion mechanical cooling. Three different operating regimes are therefore possible:■ TOTAL FREE COOLING: when the external air temperature is sufficiently low to bring the water to a value which fulfils the cooling requirements, the Free Cooling circuit functions without the intervention of mechanical cooling. This is the maximum energy-saving scenario as the compressors are never in service.■ PARTIAL FREE COOLING: when the external air temperature is insufficient to maintain the water at the desired temperature, in addition to the Free Cooling circuit function, mechanical cooling can intervene for the period strictly necessary to meet the cooling requirements. This too is an energy saving situation, even if the savings are not as high as the preceding example.■ NO FREE COOLING: when the temperature of the external air is too high for the water temperature to be sufficient to meet the cooling requirements, operation is completely given over to mechanical cooling, cutting out the Free Cooling circuit. Thanks to the head pressure control valve of the water-cooled condenser which allows regulation of the condensing temperature to 35°C, reducing the power draw of the compressor, it is still possible to obtain a reduction of energy consumption compared to a normal direct expansion system.

Free CoolingGreen Energy TechnologyGreen Energy Technology

Free CoolingTHE USE OF RENEWABLE ENERGY

The Free Cooling air conditioners are fitted as standard with:

■ An innovative control algorithm integrated into the SURVEY microprocessor permits energy savings of over

50% to be made compared to a normal direct expansion unit.

■ An AUTOADAPTIVE SETPOINT function which in addition enables the regulation of the dry cooler fans

serving the unit to obtain always the best set-point of the water temperature as the external temperature

changes. This regulation also permits the energy saving to be increased by making the fans function at partial

load for most of the time.

■ An EEV electronic valve.

■ A head pressure control valve of the water-cooled condenser which enables the water temperature to be

regulated to 35°C, reducing the power draw of the compressor.

■ A hot-gas injection, pressure-actuated regulating valve to prevent the simultaneous functioning of the two

cooling sources from freezing the condensate.

Two SourcesGUARANTEED CONTINUITY OF OPERATION

Two SourcesTwin Safety TechnologyTwin Safety Technology

The criticality of some types of plant, such as Data Centres, requires safety measures that prevent interruption of operation due to equipment problems.

The “Two Sources” system guarantees continuity of the cooling function if, for whatever reason, the primary source is not available: overload, maintenance, night-time/seasonal stoppage or for any type of emergency.

This system envisages the installation inside the machine of a second cooling source, complete with its own regulation and totally independent of the primary one. Only the aluminium fin pack is common to the two sources, thus enabling both to reach very high heat transfer efficiency levels.

The Two Sources system is extremely flexible and, depending on the sources chosen, permits various applications:

■ DX/TS: in this application, the air conditioner has a direct expansion cooling source, with one or two

compressors, and another with chilled water. The primary source is normally the chilled water one connected

to the refrigeration plant of the building or to the district cooling system, and the emergency one is the direct

expansion connected in its turn to a remote air - cooled or a built-in water- cooled condensers. Alternatively,

the primary source can be direct expansion and the emergency one water - groundwater or aqueduct.

■ CW/TS: in this application both cooling sources are chilled water coils. The primary source is normally

connected to the refrigeration plant of the building or to the district cooling system. The emergency source

can be connected to a dedicated water chiller or to water - groundwater or aqueduct.

The P series air conditioners offer:

■ Rigorous control of room temperature and humidity.

■ A very high ratio of cooling capacity to footprint area, which facilitates the designing of the areas to be climate

controlled.

■ Very high levels of energy efficiency, which translates into less CO2 emitted into the environment and very

contained running costs.

■ Very flexible application thanks to the wide range of accessories which can be selected.

APPLICATIONSTECNAIR LV close control air conditioners in the P Series consist of a family of units which are significantly different from normal climate control equipment due to their construction and operation characteristics.

Though optimized for use in data centres and telephone exchanges, they are equally valid in special applications such as metrology laboratories, TV recording studios, musical instrument storage areas, control rooms for electricity power stations and railway junctions and other areas in general where there are prevalent sensible thermal loads and crowding is negligible. Their application is also ideal in widely varied industrial sectors: optics, electronics, electro-medical equipment, electronic equipment production, musical instrument production etc.

G Series AIR CONDITIONERS FOR LARGE DATA CENTRES


APPLICATIONSTECNAIR LV air conditioners in the G Series consist of a family of units specially designed to exploit the plant characteristics of the latest generation of large Data Centres.

In the design of air conditioning equipment for large Data Centres, the necessities of cable housing and for the distribution of the enormous quantities of air required to cool the servers have made it necessary to raise the height of the false floor to now reach the current 600-800 millimetres. This creates an ample space below the air conditioner destined to the installation of the plinth. This large space under the raised floor was therefore considered as the housing for the discharge fans. The air conditioners are supplied in two separate sections: the under-base containing the discharge fans to be installed under the floating floor, and the treatment unit with the exchanger coil, filters and the electrical panel.

This large space under the raised floor is used to house the supply air fans. The air conditioners are therefore supplied in two separate sections: ■ The treatment unit with enlarged heat exchanger coil, filters and electrical panel.■ The plinth containing the supply air fans, to be installed under the raised floor. The plinth with the fans is supplied to match the height indicated in the order from the customer.

The two sections, shipped separately, are easy to install on-site as they require only electrical connection of the two junction boxes in the air conditioner and the plinth.

Without increasing the footprint area but only using the available space, the following important advantages are

gained:

■ At equal footprint area of the air conditioner, the heat exchanger coil can be sized using also the internal space

left free by the fans. The frontal section of the coil can thus be increased by about 40-50%, reducing the air

side pressure drop and therefore the energy consumption of the fans.

■ The increased size of the air filters, installed before the cold water coil, allows for a significant reduction in

pressure drop and their less frequent replacement for maintenance.

■ An increase in the energy efficiency of the fans which, installed in the plinth, expel air horizontally and completely

free of obstacles.

G Series

In order to satisfy these requirements, the R Series air conditioners have been designed and constructed to have

the same dimensions as the racks, with rear suction from the hot corridor and front supply into the cold one, with

the following advantages:

■ Use of the space freed up in the racks and therefore cold air is distributed as close as possible to the server i.e.

where the heat is generated.

■ Horizontal air suction and also horizontal air supply: the air flow therefore does not change direction inside the

machine, so avoiding the relative pressure drops and with an important consequent reduction of the power

draw of the fans.

■ Front and rear accessibility for easier maintenance.

■ Cooling, hydraulic and electrical connections from above or from below.

R Series AIR CONDITIONERS FOR LARGE DATA CENTRES

IN-ROW INSTALLATION

APPLICATIONSTECNAIR LV air conditioners in the R Series consist of a family of units specially designed and constructed to have the same dimensions as the racks.

In the design of air conditioning plant for large Data Centres, the reduction of energy consumption is of ever increasing importance. For this reason the following concepts have become consolidated international standard practice:■ The racks containing the servers are more often positioned according to the “hot corridor aisle” and “cold corridor/aisle” layout.■ The working air temperatures are now allowed to go up to 30-35°C in the hot corridor and 20 25°C in the cold one, with very low humidity (never above 30%). Consequently, also the water temperature is allowed to rise up to 20-28°C, using the Free Cooling system to the best effect.■ Server capacities keep going up while their dimensions keep going down. This means that more servers can be installed in a rack so that some of these racks, remaining empty, can be removed. At the same time the heat dissipated rises and more capacity is required from the air conditioners.■ The servers work day and night albeit with a night time reduction of their capacity. It is therefore essential for the air conditioning installation to have an efficient modulating cooling capacity control and to be designed for minimum energy consumption and minimum environmental impact.

Evolving technology has created the necessity for ever greater exchange of data, increasing exponentially the concentration of electronic equipment inside Data Centres. Infrastructure limits and constantly increasing energy costs have therefore redefined the standards of design and development of Data Centres, making efficiency and energy saving the key concepts for the choice of Close Control air conditioners.

In order to better define the abstract concepts, four main indexes have been created:

■ CAPEX – INDEX OF INITIAL INVESTMENT CAPEX (CAPital EXpenditure), is the money used to buy fixed assets of an operational

nature i.e. investment in capital assets. CAPEX is found on the cash flow statement and is

obtained from the difference of the gross values of the materials capitalized (noted as

“Investment in Plant, Property, and Equipment”) in a given year and the preceding one.

■ OPEX – INDEX OF OPERATING COSTS OpEx (OPerating EXpenditure) is the cost necessary for running a product, business or a

system. The selection of an air conditioning plant with a high degree of efficiency and

sustainability - which can optimize its own operation to suit the real requirements of the

system thus maximising its efficiency and decreasing its CO2 emissions to a minimum –

enables very high OPEX index levels to be achieved.

■ PUE – INDEX OF ENERGY EFFICIENCY PUE (Power Usage Effectiveness) is a measure of how efficiently a computer Data Centre

uses its electrical energy. It is a parameter which explains how much electrical energy is

used by IT equipment compared to other auxiliary services such as air conditioning, lighting

or UPS losses. PUE is the ratio of total power used by the Data Centre facility (PT) to the

power used only by IT equipment (PIT). A PUE value approaching 1 indicates an optimal

level of efficiency. An air conditioning plant with reduced energy consumption and, where

possible, advanced energy saving systems such as Free Cooling, dramatically reduces the

PUE index.

■ DCiE – INDEX OF IT EQUIPMENT EFFICIENCY DCiE (Data Centre Infrastructure Efficiency) is the inverse of PUE. It is the percentage value

derived by dividing information technology equipment power by total facility power. As with

PUE, an increase in DCiE is directly related to the efficiency of the air conditioning plant.

33High Density Data Center

The absolute reliability of TECNAIR LV air conditioners is guaranteed by design processes using computerized thermodynamic modelling, tests carried out in advanced R&D laboratories, the use of latest-generation materials and components, advanced production techniques in a modern facility and a certified Quality System which conforms to ISO 9001 standards.

Thanks to originality, design and attention to the requirements of the market, new solutions for application problems can be found by using TECNAIR LV air conditioners in order to:

■ OPTIMIzE INFRASTRUCTURE The wide range of models and their combined accessories makes it possible to design

modular air conditioning plant capable of being fully integrated into the Data Centre. The

minimum footprint area of the units and the modulating operation features of the components

enables solutions to be tailor-made to fulfil the effective requirements of the infrastructure,

as well as guaranteeing the possibility of future expansion without high added costs and

increasing the CAPEX index of the Data Centre.

■ REDUCE OPERATING COSTS A fundamental requirement for an increase in the OPEX index of every Data Centre is the

guarantee of continuous service and therefore the total reliability of the infrastructure.

The combination of our investment in Research and Development, together with the

highly reliable main components of the units and the simplified manufacturing processes,

make TECNAIR LV air conditioners the perfect choice for new-generation Data Centres.

■ IMPROVE ENERGY EFFICIENCY AND SUSTAINABILITY The constant increase in the amount of electrical power used as a result of the growth of the

digital world, has made it necessary to improve the energy efficiency of the plant, in addition

to reducing its impact on the environment. The ever-increasing use of renewable energy

sources and low energy consumption components make TECNAIR LV air conditioners the

most competitive choice for Data Centres in particular. The Free Cooling air conditioners, EC

technology components and software specially designed to reduce power draw together

enable savings of over 50% to be made compared to the previous generation of Data

Centres.

■ OBTAIN THE BEST RESULTS WITH GUARANTEED PERFORMANCEThe first step in obtaining the best possible result with the minimum capital investment is the

reassurance that the performance of the equipment used in the infrastructure conforms to

the project. TECNAIR LV is therefore proud to present its qualifications in this area:
